Android 11+ ships a native screen recorder in Quick Settings, no app needed. The details worth knowing are audio source selection and where recordings land.
- 1Swipe down twice to open Quick Settings; find 'Screen record' (edit the panel with the pencil icon if hidden).
- 2Tap it, choose audio: none, media sounds (internal), or microphone, plus 'show touches' if teaching someone.
- 3Tap Start; a countdown runs and a red indicator shows while recording.
- 4Stop from the notification shade.
- 5Find recordings in Photos/Gallery → Movies or Screen recordings.
Tip: DRM apps (Netflix etc.) record as black screens by design. For long recordings, plug in the charger, recording is battery-hungry.
